Profile

Field of work

Research within the section Evolutionary Genomics focus on the origin of biodiversity, more precisely the genomic footprints of speciation and adaptation and the link between phenotype and (adaptive) genotype. Research is based on genomic data, like genome sequence data, gene expression data and epigenetic marks as well as in-depth organismic knowledge (morphological, behavioral, epigenetic and/or ecological data). This in-depth knowledge will allow gaining a holistic representation of the evolutionary history of the organism or species group and inform further research and conservation efforts.

Research interests

My primary research interests lie in the evolutionary dynamics of speciation and in the evolution of adaptive traits. I am interested in early stage species divergence and in understanding the mechanisms that shape biodiversity. In previous studies I worked on cichlids of the lower Congo River to study different levels of spatial differentiation and degrees of gene flow in a comparative approach. In my current projects I focus on the genomic and morphological architecture and evolution of adaptive traits in Sulawesi ricefishes.

AG RICEFISH

The focus of the proposed research group is to study the link between genotype and phenotype of evolutionary adaptive traits, a vital question of evolutionary biology in the postgenomic era. The group will study the morphological and genomic basis of a unique reproduction strategy in Sulawesi ricefishes (Actinopterygii: Adrianichthyidae) called “pelvic brooding”. In pelvic brooding species, females carry the eggs in an abdominal concavity until they hatch, which is assumed to be an adaptation to a predominantly pelagic lifestyle.
